Polymer resin is more impact resistant. It is used for transparent windows in aviation and masks on astronauts' helmets. Glass is only one-tenth as heavy as a resin lens and half as heavy as a resin lens. PC lenses need scratch-resistant protective film, which can be used for children's myopia lenses or goggles.
Among them, resin lenses are the most widely used and the price is relatively acceptable. PC lens is the safest lens, but not many people use it because of its high price.
The price of glass sheets is relatively low, and they are mostly used for reading glasses. To sum up, the resin lens is actually not bad. Although resin lenses cannot be broken, you should be careful when using them. Personally, I think resin lenses are cost-effective and relatively high, so I will talk about resin lenses next. I hope my common sense can help you choose the right lens.
It can also be seen in daily life, such as plastic, plexiglass, paint, etc. Resin lens is a kind of lens synthesized by chemical processing with resin as raw material.
There is no best shot, only the most suitable one. Resin lenses are divided into ordinary, ultra-thin, ultra-thin, spherical, aspheric, color-changing and color-unchanged. 2 lens thickness is divided into: ordinary, ultra-thin and ultra-thin; According to personal preferences, generally thin lenses, the price will be higher. Generally, the lens changes color, so it can be inferred that the lens is radiation-proof, and the lens that does not change color is not radiation-proof. It is recommended to choose a color-changing lens.
